Catalytic Thia-Sommelet−Hauser Rearrangement: Application to the Synthesis of Oxindoles
摘要:
A series of 3-arylthio-1,3-disubstituted-oxindoles were prepared in good yields by the reaction of alpha-diazocarbonyl compounds and sulfenamides. The reaction involves a Rh-catalyzed thia-Sommelet-Hauser-type rearrangement.

Organoaminosilanes, such as without limitation di-iso-propylaminosilane (DIPAS), are precursors for the deposition of silicon containing films such as silicon-oxide and silicon-nitride films. Described herein are methods to make organoaminosilane compounds, or other compounds such as organoaminodisilanes and organoaminocarbosilanes, via the catalytic hydrosilylation of an imine by a silicon source comprising a hydridosilane.
